To (ZZZ whom it may coaceim: 1 i I g Be it known that I, ROBERT WERNER OBER- 'HorFER, a subject {of the King of Great Britain and Ireland, .residing at ork, in

the county of York, England, have;inven ted certain new and useful: Improvements in or Relatingto the Tuning-Pegs of Violins or like Instruments, of which the following is ing around the pegs in the peg holes, and

thus allowing the 'strings to become slack or'fiat, i. e..out of tune- More particularly the invention consists of improvements in that type of means-for the above purpose, inwwhich one of the two I peg holes'is enlargedandprovided with a brake ring or socket, adapted to grip'th'e pegand prevent its rotation in the slackening direction.

The invention is illustratedby the accompanying sheet of drawings,-to' which reference is bad in the following description,"

Figure 1 isan outside view of the peg with the brake tube in position. ,Fig., 2 is an outside viewjof' the peglwithout the" I brake tube. Fig. 3 is a longitudinalsection,

and Figs. 4 and 5 are end views ofthe brake ltube. i 1

For the sake of'clearness, .the last three figures have been drawnto an exaggerated scale.

windicates the shank ofgthe peg, and a slightly tapered or coned sleeve 6 is pinned.

or otherwise 'securedjto thepegclose to its head supplyingusaid shank with an operaj tive tapering surface, but of course 'remov able for substitutingfanother sleeve, or whenever such operation is -needed for other reasons. 1 According to, this invention, this coned sleeve 6 fits within a brake-ring 0, which is formed as a spiral or helical coil of round wire, and for which Ifindga'lvanized round wiremost' suitable; the interiorof the ring being preferablyslightly tapered to corre spond to the taper of the sleeve'jb. -This spiralcoil 0 fits within the cylindrical end (i of the brake tube 6, being received in a re' cess formed by the enlargement of the bore of'said' tube, its inner end'being secured to. the tube 6 about the rabbet fby soldering or forming a recess in the rabbet to receive the end of the wire, or other suitable means. The other end of the coiled wire is heldin r H WhatI doclaimand desire to secu re Letters Patent':is:'.

TSpeci fication,of Letters Patent. l Application filed August 1,1e1 4.f Serial 859,342 i I I I position bybeading 1e. bending the outer I end of thetube'over'inward, so asto-form'a 1 retaining rim-g, WhlCll. covers only about; g' half the thickness of thewi're.

h'ofthe tube is screwed. into the enlarged 'fpeghole ,of the instrument at thumbipiece' I side of theipeg; ,for which purpose the; middle of the brake tube is provided .with a milled or asshown a hexagonalccollari.

The peg itself may be of any kind of hard wood'or vulcanite.- r j indicatesthe'par't of the neckof the in-' strument which is recessed, to expose the middle portions of the shanksofthe Jpegs'w and to allow the upper' end's ofthe-strings to be connected to the. pegs. t '1 Owing to the brake coil 0 being formed of round wire, it bears on the sleeve 6 on a long of the peg,

"Thepeg is passed through the coiled wire into the opposite holeof the head of the in- 1 r strument. When pushed, in, the peg is. a

gripped by the coiled wire in the direction" 1 in whichthe string pulls, but not in the op? 5 i posite direction. a When thepeg is drawn out of thetube for about one thirty second of an inch, it can be turned in either direction. The string is passed through a smallhole in the cylindrical portionja 0 p I 1: the peg and 0 tuned upintheordinaryway. I o

The invention ofi'ers the following ad-' yantagesr-Thebase with which the pegs can be workedin either direction enables the Weakest handto manipulate them. Thepegs cannot slip infthe direction in'which the str ng pulls. The pegs cannot get jammed; g

The pegs canbe handled with ease while using thebow; The pegs can beifixedto the best class'instrument with t d m 11. 7 Qdisfiguring'the head of the instrument. 1

It has been previouslyrproposed to'fit the pegs ofstring musical'instrumentswith a,

conical tube orv sleeve, -and.to provide short 7 I cylinders orcones in the. thumb'pieoe side j of the instrument, split longitudinally, or to form a broad spiralband. I Ido not there:

fore claim such' but 1. A'violin tuning-peg having a shank, in combination with a-sleeve fixed on said shank and slightly tapered externally, a brake tube having a recess formed by an enlargement of its bore, an annular shoulderat the inner end of said recess and an internal bead at the outer endof said *recess,

and a "brake ring consisting of a tapering Copies of this patent niay be obtained for tube having a reoess formed by an'enlargeinentof its bore and an internal annular head at the outer end of said recess, and a helical tapered brake in said recess 1nterposed between said surface andsaid tube,

fastened to the latter at one end. and held at the other end by said bead against-expansionsubstantially"asset forth. 7 In testimony whereof, I have signed my name to this specification in the presence of two subscribing vvitnesses.
